Re: Boss 338 Wheels **GROUP BUY**
 

I'm Sorry can someone explain for me why as spacer is needed for the back wheels? Please

Re: Boss 338 Wheels **GROUP BUY**
 

What about a illustration showing how the 20x10 will fit on the rear of the trucks. Whether it be a 67-70 or 71-72. Something showing how much wheel will be inside, and how much lip will be on the outside. Can someone draw this up?

Re: Boss 338 Wheels **GROUP BUY**
 

My 68 w/the stock 68 12-bolt could use 5-5.50" back-spacing. I installed 5.50"BS wheels that required mini-tubbing the bed floor. Add an additional .725" & it would only be worse. The use of a wider 71-72 rear might work better here but I'm not sure how much clearance would be there.....

The 5.50"BS was about the max I could use on my 74 (w/stock 74 12-bolt). Again, any more back-spacing would require mini-tubbing. There might be a slight chance they'd fit but it would be close.

Re: Boss 338 Wheels **GROUP BUY**
 

Do these wheels have too much back space, if you have air suspension? I have bags on my trailing arms and bags in the front

Re: Boss 338 Wheels **GROUP BUY**
 

Yes,... if you are running 20's on the rear.
Spacers will be required with a stock rearend on the 67-72 and 73-87 trucks.
The 88-98 trucks will be fine.

Re: Boss 338 Wheels **GROUP BUY**
 

Sorry for all the questions, but I just want to make sure they will fit the look I'm after before I buy them.

With the spacer on the rear will the tires and wheels still fit inside the wheel wells?

Re: Boss 338 Wheels **GROUP BUY**
 

man glad I brought this up im still interested but just dont want to blow the cash if I have to sell them down the road cause they don't fit. so what kinda spacers would I have to run on a stepside with the 71 axle and 79 front brakes with drop spindles

Re: Boss 338 Wheels **GROUP BUY**
 

on one of the pages someone mentioned that they used 1 inch spacers on a 20 inch wheel.

Re: Boss 338 Wheels **GROUP BUY**
 

Im confused.... I thought the only problem was with the rims not fitting the the front hub, and now the rear bs wont work? Its late, Im tired, I would really like to be in on this group buy, but only if the wheels are going to fit. Ill check in again in the morn..,....

Re: Boss 338 Wheels **GROUP BUY**
 

that's the thing about these trucks I am conveting from the 6 lug on a 68 to the 5 lug just because the wheels I had priced out were 3500 bucks for a simular wheel as these no tires just bolt on and go I really don't like spacers but you have to do what you have to do

Re: Boss 338 Wheels **GROUP BUY**
 

yeah I am out on the spacers drop me from the list thanks though

Re: Boss 338 Wheels **GROUP BUY**
 

Man I have the stock rearend 70 model with just a 2 4 lowering kit I really wanted these wheels is there no way around the wheel spacers?

Re: Boss 338 Wheels **GROUP BUY**
 

I'm pretty sure you won't need spacers to run the 20x10's, but I'm sure someone who has them can clarify this.

Re: Boss 338 Wheels **GROUP BUY**
 

Look here:

http://67-72chevytrucks.com/vboard/s...352320&page=12

Go down to Benji's post,it doesn't look like he is running a rear spacer on the 20x10's. He may be running a 1/4" spacer like he did on the front but I can't tell for sure by the pics.

We will know for sure in a few days.

Re: Boss 338 Wheels **GROUP BUY**
 

The 20x8.5's will be fine for the front, if they address the "hub fitment issues".
The rear will need spacers.

Everyone is so "blinded" by the cheap price,... that they just forget all the other stuff.
Most people running Coys 20x10's have a choice of 5" or 5.5" backspace.
These wheels have a 6.225" backspace.

Get out your tape measures and check out your trucks for yourself.

Re: Boss 338 Wheels **GROUP BUY**
 

No offense, but what's with people wanting to drop hundreds of dollars on rims without even knowing what backspacing they need? Wheels aren't like deodorant where you can just grab whichever one looks most attractive on the shelf.


Exactly. If you want Coy-like options, you pay Coy-like prices. This deal is for wholesale cost on wheels that are already amazingly inexpensive. Don't like it? Move on. :)

Here's a direct link to Benji's post, which shows the 20x10s on the rear of his '72 without any apparent spacers: http://67-72chevytrucks.com/vboard/s...&postcount=299

Below are a couple pics from Benji's post. YMMV.

Re: Boss 338 Wheels **GROUP BUY**
 

Here's a quote from Benji:
"here is my 72 bagged, still have to cut out the front fenders and tube out the back to it will go lower"

I think he means tub out the back.
I just measured up a truck with 20x10's with the narrower 67-70 rearend housing.
His backspace numbers were 4.75 inches.
These wheels are 6.225" BS.

Good Luck guys.

Re: Boss 338 Wheels **GROUP BUY**
 

My impression is that in order to drop it lower he needed more height in the tubs, not width. In another post, he said, "i still need to cut the front fenders and modify my bed to go lower when i slam the bags," which is pretty much the case with everyone wanting to "lay frame" or whatever the young whippersnappers call it, at least as I understand it. If width was an issue, I don't think it would sit as low as it does in the pics. I am not saying that people won't need spacers, and I'm not arguing in any way -- just trying to accurately report what others are experiencing.

To be clear: There is no substitute for measuring your own setup and determining exactly what you need.

I'm curious, Keith ... since you started the original behemoth Boss 338 thread, do you know what the owner of the truck you photographed did with the rear wheels? And you've got these wheels, too, so what have you done about the rear backspacing? Sorry if this is answered elsewhere, but I can't take time at work to read through the 28 pages in that thread plus search through your other posts elsewhere. :)

Re: Boss 338 Wheels **GROUP BUY**
 

I think an 'easy fix' for this backspacing 'issue' would be to just order 20x8.5 all the way around and not have ANY issue with backspacing, at least that's what I plan on doing.
Plus it makes good for rotating tires, ;) functionality and good looks.

Re: Boss 338 Wheels **GROUP BUY**
 

Excuse my ignorance...why would someone order different backspacing between the front and back? Can someone give me a quick and simple explanation of what backspacing is? Is it to do with how close the lip of wheel gets to the fender? Would either of these wheels fit with a stock 72 2wd rear end?

Re: Boss 338 Wheels **GROUP BUY**
 

The truck I photographed had 20x8.5's on all four corners. He had a spacer on the back.
I haven't mounted my wheels on a truck yet. My 69 is still 6-lug. I plan to run spacers,... I always have.
I think without them they will contact the wheel tubs.(especially with the 67-70 rearend). My blazer has the wider 71-72 rearend and I have a 5.5" bs wheel on it,... and it is close on the inside. No room for another .725" of backspace.
